High Precision Double-Sided Lapping Polishing Machine - Lab Research | UNIPOL-160D

Product Description

The UNIPOL-160D Double-Sided Lapping and Polishing Machine is primarily designed for the double-sided precision lapping and polishing of sheet materials such as quartz wafers, sapphire, ceramics, glass, infrared optical materials (e.g., crystals like Zinc Selenide, Zinc Sulfide, Silicon, Germanium), and metals.

This machine employs a worm gear reducer as its transmission mechanism. Through a gear set, it achieves rotational motion of the upper, middle, and lower spindles at different speeds and in different directions. This configuration generates a speed differential and relative motion between the upper and lower lapping/polishing plates and the intermediate sun gear. Samples are placed within the inner holes of the carrier planetary gears, which are driven by the sun gear, thus enabling double-sided lapping and polishing.

The UNIPOL-160D Double-Sided Lapping and Polishing Machine offers versatile processing capabilities. It can be operated using lapping plates with abrasive slurry for sample lapping, or alternatively, it can utilize a polishing plate with sandpaper for sample grinding.  When using sandpaper, the process involves attaching sandpaper to a lapping/polishing film, and then adhering the lapping/polishing film onto the polishing plate for grinding and polishing operations.

The machine is capable of processing multiple samples simultaneously, resulting in high lapping and polishing efficiency. It is well-suited for high-volume sample processing and small-batch production in factories.

Product Main Features:

1. The rotational speed is controlled manually by adjusting the frequency of the frequency inverter.

2. Double-sided lapping and polishing of up to 4 substrates with a maximum diameter of Ø2 inches can be performed simultaneously.

3. Double-sided thinning of thin wafers/sheets is achievable.

4. Ideally suited for double-sided lapping and polishing of Si, Ge, and oxide single crystal substrates.
